They aren't connected. Want to know how I know that? I actually looked into what transhumanism actually is. I read works by actual transhumanists.
This is similar to your threads where you dissect words down to their roots and claim that there are insidious meanings cloaked in the words. You took a bible passage out of context. genesis 3-5 in context is the serpent convincing Eve to eat of the fruit of knowledge to become equal to God. Transhumanism has nothing to do with rising to the same level as the Christian God. The purpose is to improve humanity through technology. Meaning humans could become more resilient, stronger, and live way longer lives.
Believe it or not Christianity is only one of multiple ideologies that influence modern philosophy.
